There is one Mini-USB interface on SIM18-EVB, which is transferred to UART by a USB to
UART chip CP2103 on the EVB board. User need to install CP2103 driver in their PC first, then
connect the EVB board to the PC by a USB cable, and set S301 switch be VBUS to power the
SIM18-EVB.
Please download the latest CP2103 driver according to the PC’s OS from the following link:
http://www.silabs.com/products/mcu/pages/usbtouartbridgevcpdrivers.aspx
Or contact SIMCom support for it.

zWAKEUP: When SIM18 in full-on mode, the LED is on, while in sleep or KA mode, the
LED is off.
zTIMEMARK: The LED is on after SIM18-Z01 firstly going to full on mode,
Buttons:
zRESET: When RESET button be pressed, SIM18 will go into sleep mode.
zON_OFF: When ON_OFF button be pressed for about 100ms, SIM18 will wake up from
sleep mode.
Working states of status LED are listed in following table:
Table 5: Working state of status LED
Name Description STATUS
Q1 POWER ON/OFF indicator On: power ON
Off: power OFF
Q2 WAKEUP status indicator On: Module runs normally
Off: System is powered down or module runs in sleep mode
Q3 TIMEMARK indicator On: Module runs normally, if ROM firmware patch is added, the
LED will blinking at a certain frequency when location is fixed.

bus cable, and set S301 switch to VBUS, then “Silicon Labs CP210x USB to UART
Bridge (COMX)” will appear in the device manager:
Figure 18: USB driver installation step9
5.2 Connecting and run
After installing CP210x USB to UART Bridge driver, the following operations are:
(1) Connect the active antenna to the RF connector, and set the VCC_ANT S302 switch to
VCC_3V, set the PWR_LF S101 switch to VCC_3V.
(2) Connect the SIM18_EVB to PC via the USB cable, and set the PWR_IN S301 switch to
VBUS, the POWER led will turn bright.
(3) Press ON_OFF button, the WAKEUP and TIMEMASK leds will be on, this means SIM18 has
been running on full on mode.
(4) Use “SIMCom NEMA GPS DEMO TOOL” or other NMEA tools to evaluate SIM18
performance. SIM18 default baud rates in NMEA mode is 4800 baud.
(5) Press nRESET button to control SIM18 going into sleep mode
(6) Set the PWR_IN S301 switch to DC_5V to power off the SIM18-EVB, the POWER led will
be off.
Note: Power supply off-time is suggested to be over 10 seconds to next power up in order to
clear all internal backup RAM content.
